My mom and I stayed at a CBR Pirate room for 6 nights/7 days with my then 4.5 and 1 yo boys. First couple of days the walk was fine--the resort is beautiful and the pirate rooms are great--but after that it became a hassle. We ended up driving the car back and forth to OPR for food and pool time--pain with wet swimsuits LOL. If you are planning to spend anytime at the resort (the pool area is fantastic for the kids) and will be there for more than 3-4 nights, personally I would book preferred.
I also would request 1st floor with kids and strollers (this is what we had!).
